ok so i tore down my 2.0 this week and have been planning on doing a hybrid set up... ive read that typically a cracked 2.0 head is very common...mine is cracked in the typical spot starting out by the spark plug heading towards the valve, and not sure if i goes past the valve or not. before the tear down the car ran very well other then the spun bearing and didnt consume oil, so my quesion is what are my options? do i get the head cleaned, get a valve job and resurfaced or do i try to find some 2.5 heads or a set of uncracked 2.0 heads if such a pair exists?
